No lenses on t247 question...

[slowngreen]

With the lenses being about 1/2", if I were to run no lenses, would alot of light be lost behind the housing? Since their not like a black box with the glass in front of lenses.

Yea. A lot would be lost.
A cheap lux meter will tell you how much.

I left them on. I was swapping out some leds and just wondered if it would get rid of how "spot lighty" they are but I dont want to lose any light.

You could play with some diffusion I suppose. Look for the very thinnest you can find.
The thinnest cheapest I found was actually “clear “ shelf paper.

How high above the water line do you run them?

I have them about 11". I tried them at 8 before but it is alot better now at 11.

I never thought about removing lenses for s 247 it’s usually for vispars and Mars Aqua [emoji848]

Try diffusing it with a piece of frosted acrylic. I was going to use t247s but didn’t want to build a diffuser for them.
